Abstract

Selon l'invention, en fonction des informations d'utilisateur stockées au niveau d'une unité de mémoire d'informations d'utilisateur, une unité de traitement de création de groupe (133) évalue la similarité entre des attributs d'utilisateurs, et crée un groupe comprenant une pluralité d'utilisateurs évalués comme étant similaires. Sur la base de ce résultat, lorsqu'un sujet d'accès fait l'objet d'un accès, une unité de traitement d'orientation d'utilisateur (135) augmente un score de recommandation d'un premier point dans le sujet d'accès dans le groupe auquel appartient un utilisateur accédant. De plus, lorsqu'une évaluation du sujet d'accès est enregistrée, l'unité de traitement d'orientation d'utilisateur (135) modifie le score de recommandation d'un point correspondant au contenu de l'enregistrement d'évaluation dans le sujet d'accès dans le groupe auquel appartient un utilisateur enregistrant l'évaluation. Sur la base du score de recommandation modifié dans le sujet d'accès, des informations de sujet d'accès de recommandation sont ensuite transmises à un dispositif de terminal d'utilisateur d'un utilisateur qui appartient à chaque groupe. Ceci permet un accès efficace à un sujet d'accès utile à un utilisateur.
